Sighting Zero at what distance ???

Hi there again friends, i have finally got my Long Range Rifle setup together and was wondering what distance to Zero it at ?? It's a Sendero in .300wm with a Burris Black Diamond 8-32 scope and i intend to shoot out to 1000yards .....at what distance should i zero at ?? Also the scope has the Mildot Plex which has those yardage markers for 200 300 400 500 600 yards, will they be of any use when zeroing at distances greater than 100yards ??

"at what distance should i zero at ?? Also the scope has the Mildot Plex which has those yardage markers for 200 300 400 500 600 yards, will they be of any use when zeroing at distances greater than 100yards ??"

Mate you just have to start somewhere and see how it goes. But if you want to shoot to 1000 yards then you are going to have to dial up.

I am not a fan of yardage markers on a scope reticle but with that scope I would zero it in at 100 yards. I would then shoot it at all the range markers listed with your chosen load and see how it compares.
Then I would work out the drop at 1000 yards and see how far off the mark you are at that distance when you dial up.

Once you have all this information you will then have a better idea of the trajectory of your load. This will help you decide on where to go fron there.

I think the 300 win mag will shoot to flat to use the scope with a 100 zero . a 100 zero is more for non magnum velocities . use a 200 zero and your ballistic marks will then be 300 , 400 , 500 , top of the heavy post will be 600 . as the other fellow said to get to 1000 you will need to dial up .

this advice is for the balistic plex . you are using mildot plex . sorry about this .

Reason: I gave info for wrong reticle

If you're considering going out to 1000 yards, I'd highly recommend using either Burris Signature rings to add some MOA to it or a 20 MOA base. My last two rifles I used the Burris Signature rings and each required +10 in the back and -20 in the front to get the crosshairs "right on" a 200 yard zero without ever touching the elevation screws. If you do this, you won't "use up" your vertical adjustments just bringing the scope down to its initial zero.

I'm sorry , I was talking about the ballistic plex reticle . I've had these before and was going from memory . I just looked up the black diamond 's reticles . the 300 does call for a 100 zero . they are not using the top of the heavy post for a yardage for the 300 mag , but you could . here is a link to that info .
